The Scarlets travel to face Agen tomorrow after defeating the French side at Stradey Park last weekend.

"If we can go there and win on Saturday it will put us in a great position - but it's a huge task," said Jenkins.

"There'll be a reversal of roles this weekend.

"The expectation and pressure is on them, the whole of Agen will be expecting a home result.

"Saturday is a great opportunity for us - this weekend is critical and there is a confidence in our team."

The Scarlets are waiting on the fitness of second row Chris Wyatt, but otherwise Jenkins has named an unchanged team.

Wales wing Mark Jones continues his recovery from a knee injury with a place on the replacements bench.

While the Scarlets are flying the flag in Europe, the Neath/Swansea Ospreys are licking their wounds after losing their three Heineken Cup matches this season, including a defeat against tonight's opponents Toulouse last weekend.

Although the Ospreys have no chance of qualification, coach Lyn Jones has promised he will be aiming to win his next three games, starting with the match at the Gnoll tonight (7.45pm).

"Although we have lost to the other three teams in the group, we want to put things right over the next three fixtures," said Jones.
